TYPE-WRITING- MACHINE.

Specification of Letters Patent.

Patented Apr. 9, 1918.

To all whom it may concern:

Be it known that I, CLIFTON B. CoRnLL, a citizen of the United States,residin in New York city, in the county of New ork and State of NewYork, have invented certain new and useful Improvements in Type- WritinMachines, of which he following is fication.

This invention relates to sheet collating devices for typewritingmachines of the class in which sheet impaling pins or studs are providedto be projected through perforations in the side margins of work sheetsarranged on a collating table, for alining the sheets or holding them inadjustable posi tion. The studs may be withdrawn from the work sheetsafter the latter have been adjusted, to permit the sheets to be advancedover he platen of the typewriting machine. As the impaling pins may bemade to fit snugly in the openings in the sheets to ob-; tain a positiveand exact alinement, it is important that the pins should be withdrawnby a straight line movement perpendicular to the sheets in order toprevent tearing of the sheets or displacement of the latter as the pinsare withdrawn.

An object of the present invention, is to provide improved means forwithdrawing the impalin pins in the manner stated. In practising tieinvention the sheet collating table, which may be located at thedelivery side of the platen to extend upwardly and rearwardly beyond theprinting line, may be provided with a row or rows of impaling pinsarranged to enter rows of openings provided along the side margins ofthe work sheets. In order to support the pins and permit them to bewithdrawn in a direction normal to the work sheets, each row of pins maybe carried on a shiftable support located behind the table, with thepins projecting through openings in the table, which openings may serveto position and guide the pins. Said supports may be actuated by cams toproject or withdraw the pins. The cams may be in the form of inclinedslots in actuating devices, mounted to slide on the rear face of thetable, the slots arranged to receive studs on said supports so that thesliding movement of the actuating devices may serve to shift thesupports toward and from the table to project and withdraw the impalingpins. The actuating devices may be operated by a key connected theretothrough suitable mechanism, as for example, a rock shaft carrying thekey, pinions on said shaft, and racks on the actuators driven by thepinions.

Other features pear hereinafter.

In the accompanying drawings,

he roller platen 10 is mounted on a platen axle 11, journaled in theends 12 and 13 of the platen frame, which also comprises ,an inclinedpaper-shelf 14 at the intake side of the platen. Type-bars 153 (Fig. 4)may be operated by the usual mechanism to cause thetypes thereon toprint at the front face of the platen. Front and rear feed rolls 16 and17 bear against the under side of the platen and coiiperatc therewith tofeed the work-sheets around the lower side of the Jlaten and upwardlypast the printing line.

he feed-roll shafts are mounted on levers 1S, jourualed on a rod 19,said levers being actuated by a rock shaft 20 having cams or flatsoperative when said shaft is rocked to spread the arms 21 of saidlevers, and thereby throw the feed rolls oil the platen. A feed-rollrelease key 22 is connected through a link 23 to a rock arm 24: on theshaft 20, whereby, when said key is depressed, the shaft 20 is rockedand the rolls 18 and 17 are moved downwardly away from the platen. Thefeed rolls are restored to the platen by springs (not shown) when anupward pressure is applied to the key 22.

The platen may be rotated either by the hand-wheels 25 on the platenaxle or by the usual line-spacing mechanism. The latter comprises aline-spacing lever 26 operable to move rearwardly a slide bar 27carrying a pawl to drive a line-space ratchet wheel 28 connected withthe platen.

The above described parts may be of the usual construction, common incommercial Underwood typewriting machines.

The sheet collating table 30, may comprise end sections 31 and 32 and aninter ,mediate connecting plate 33. The'end plates 31 and 32 are'adustably connected to the plate 33 by means of screws 34 extending throuh elongated slots 35 in said end plates and c mping the latter to theplate 33. By loosening the screws, the ends 31, 32 may be adjustedlengthwise of the plate 33 to ad just impalin pins or studs 36 forsheets 0).

different wi ths, or for adjusting the position of a sheet held by onerow 0 pins relative to that of a sheet held by the other row of pins.The collating table 30 is mounted on the platen frame in position toextend upwardly and rearwardly from the platen so that work sheets a, b,on the laten may have their leadin ends overlie tl ie table 30,

permitting the s sets to be arran ed and alined on the impaling studs36. cans for mountin said table, comprises brackets 37 on the p atenends, a tie rod 38, connecting said brackets, and a rod 39 extendingbetween the platen frame ends. Brackets 40, supported on the rods 38 and39 have forwardly extendin arms 41 secured to the sheet collating ta le,as by means of clampin screws 42 extending through vertical slots 43 inthe ends 31 and 32, and threaded into the bracket arms 41. Thisconnection permits adjustment of the table toward and rom the platen,the screws 42 clamping the table in adjusted position on the saidbrackets 40.

The impaling studs 36 are arranged in rows adjacent the ends of thetable 30, each row of studs being carried by a support 44 behind thetable so that the studs extend throu h openings 45 in the table andproject a ve the surface of the table and perpendicular thereto. Thesupports 44 are shiftable toward and from the table to project andwithdrawthe studs, b means of actuators 46 having cam slots 4% toreceive headed pins 48 extending through said cam slots and secured tothe supports 44.

The actuators 46 are inounted 0n the rear face of the table for slidingmovement thereon, toward and from the platen; such mounting'comprisesheaded ins 50 extending through longitudinal s ots 51 on the bottom orrear wall of the actuator into guide blocks 52 secured to and projectingrearwardly from the collating table near the upper end thereof. Thelower ends of the actuators 46, are in like manner guided and supportedb pins 54 extending through slots 55 in e actuator, said pins 54 beingmounted on angle plates 56 attached by i turn the feed rolls l6 and 17for holding screws or bolts 57 to an angle bar 58, secured to andextending lengthwise of the table along the bottom edge thereof. Withthis construction, the actuators 46 are ermitted to slide up and down onthe table but are held against either lateral movement or movementtoward and from the table.

Means for operating the actuators 46 comprises a key 66011 a rock shaft61 to which are fixed pinions 62 runnin in mesh with racks 63 onactuators 46. he rock shaft 61'is mounted at the back of the 001- latingtable, being journaled in bearing blocks 64, secured to the rear face ofthe plate 33.

When the key is thrown upward to the position shown in Figs. 1 and 3,the pincarrying supports 44 are held closely against the rear face ofthe table so that the ins 36 project through the openings 45 intogosition to permit the arrangement of the work sheets thereon. Towithdraw said ins, the key 60 is swung downward to the ig; 4 position,thereby rotating the ElDIODS 62 and operating the racks 63 so t at theactuators 46 are slid upwardly or away.

from the laten. By this movement, the cams 47 sliding along the pins 48move the latter rearwardly, that is to say, the carriers 44 are movedaway from the table in a direction perpendicular thereto, thuswithdrawin the pins 36 from the work sheet. It wi 1 be seen that the suports 44, owing to the pins 36 being held an guided in the openings 45 inthe table, are only moved in a direction per endicular tothe table. Thepins 36'are thus withdrawn without tearing or displacing the sheeets.

To permit the arrangement of the work sheets, the feed rolls 16 and 17may be thrown off the laten by depressing the key 22. The first s est 6may then be dropped on the paper shelf 14 and advanced around the undersurface of the platen to bring the leading end of the sheet over thecollating table 30. The sheet, by means of the perforations in its sidemargin may then be impaled on the projecting studs 36 whereby the sheetis alined and squared to the platen in osition to receive the first lineof typewritmg. An outer sheet a with an intermediate carbon sheet maythen be introduced between the first sheet and the paper shelf 14 andadvanced to position to be written upon, the sheet bein adjustedlon thestuds 36 and thus alined n the same manner as the first sheet. Thesheets as thus arranged may have their leading ends at differentpositions of advancement depending on the character of the sheets and tht position at which the typewritten entries are to be made onthe-several sheets. The sheets being thus arranged, the key 22 is liftedto rethe: sheets to the platen in their relativeposn :ion of adjustment.lhe key is now thrown down to withdraw the studs 36 so U: n the sheetsmay be advanced over the coliulillg tahhwithout interference from.

said pins as the platen is rotated.

'iulions may be resorted to within the scope of lhe invention, andportions of the improi'cnieuts may he used without others.
